	RE 5015 Spring Over Conversion Kit — This conversion kit moves the leaf spring perch to over top the axle, markedly increasing lift and flexibility. Spring over Axle lifts retain a stock-type ride quality by retaining the original spring. Modifications for this lift include removing original spring perches, welding of new perches, and other adjustments. A CV-type driveshaft is strongly recommended for this application.
